This code has been taken from zezutom at http://zezutom.blogspot.com.es/2012/04/mobile-apps-on-spring.html but I wanted to execute it from mvm (mvm tomcat:run). As he said, this app works fine with tomcat7, so I've added this feature.
Just download it,
mvm tomcat7:run and go to http://localhost:8080/spring-mobile/
Have a nice day :)
